# Mechanical Elements — Acronyms, Conveyors, Station Codes

## Overview

Reference page for the physical hardware vocabulary used in automated Mecalux installations: machine acronyms (ES / EN), conveyor types and their WMS tracking behaviour, miniload (TK) nomenclature, and the station-code matrix across French, Spanish and English. This page is the cross-walk between shop-floor labels and the station types registered in EasyWMS.

## 1. Machine & equipment acronyms (ES → EN)

All Mecalux mechanical acronyms are in Spanish; the translation matters because GALILEO logs, vendor drawings and EasyS labels mix languages.

## 2. Conveyor terminology & WMS tracking behaviour

Conveyor type drives whether EasyWMS can reliably track a container on the conveyor, and therefore how it should be modelled in EasyS.

| Type | Capacity | WMS tracking |
|------|----------|--------------|
| **LRA** (Buffering roller) | 1 container | Tracking moves LRA → LRA on each hop; container can be **stopped** on an LRA |
| **LRC** (Continuous roller) | multiple containers | Containers advance until the end sensor trips — **tracking is generally lost** on LRC |
| **LRAB** (Scale roller) | 1 container | Acts like LRA, with an integrated scale (weight verification) |
| **LTM** (Cross transfer) | 1 container | 90° change of direction; on multidirectional tables set `routing options = 1` for each feeder conveyor |
| **LRD** (Diverting outlet) | — | Oblique outlet — splits flow off a main line |
| **LRI** (Angle induction) | — | Oblique inlet — merges flow onto a main line |
| **LBC** (Belt conveyor) | multiple containers | **Tracking lost** when a container passes a belt conveyor |
| **LRL** (Free roller / gravity) | — | **No tracking** on LRL; WMS treats the position as a **buffer** (typically with an outbound station upstream) |
| Pedestrian passage | — | Elevated walkway — not a conveyor; no container flow |

**Practical consequence:** LBC and LRL segments behave as "blind" zones. If a PS (shipping conveyor) outputs onto an LRL, WMS closes the tracking at the PS and considers the container parked in a buffer.

## 3. Station codes — FR / ES / EN matrix

Station codes are shared by EasyWMS and GALILEO. Each station is uniquely identified by the couple **(Type, Number)**. Keep this table as the source of truth when cross-referencing documentation between regions.

## 4. Miniload nomenclature (TK / ML)

Machine code reading rules for miniloads:

- **ML** = Miniload
- **B** (after ML) = **Bicolumn** (absence of B = single column) → e.g. `ML-100` (single), `MLB-100Q` (bi)
- **EPSF** = Extracteur Pelle Simple Fond — **1 charge** per extraction cycle (pelle = shovel, single depth)
- **EPDF** = Extracteur Pelle Double Fond — **1 charge**, double-depth rack
- **ECDF** = Extracteur Courroie Double Fond — **2 charges** per extraction cycle (courroie = belt, double depth)

**Rule of thumb:**
- "Pelle" (shovel) extractors handle **one charge** at a time
- "Courroie" (belt) extractors can handle **two charges** at a time — they drive the logic for channel filling and double-depth putaway

The miniload model (from the installation layout) dictates the entry/outbound table configuration in EasyS (see [Galileo Simulation](../operations/galileo-simulation.md)).
